PLURAL-RECORD PrionoonAPn'.

Application filed December 19. 1912, Serial No. 737,598. Renewed June 25. 1917. Serial No. 176,922.

To all wh'om, it may concern Be it known that I, Gannon W. Bowen's, a citizen of the United States. and resident of Somerville, in the county of Mid'tllesex and State of Massachusetts, have invented certain new and useful Improvements in Plural-Record Phonographs, of which the following is a specification.

The present invention relates to machines of the sort known as phonographs, graphophones, or talking machines, which are adapted to reproduce sounds by the coopc'ation of a stylus or other repro ducing element with a member, known as a record, whi h is carried by a moving part of the machine and is so prepared that, when relative motion occurs between the record and the reproducing clement, it may vibrate the latter in a manner corresponding to sonorous vibrations. Such machines are generally provided with amplifying horns by which the volume of sound produced by the reproducing means is enlarged.

The principal objects of my invention are three in number :first, to provide improved means for carrying a plurality of records and reproducing; the sounds recorded upon them in succession without stoppin themachine and without shifting the records; second, to make the record holder constitute part of the amplifying horn; and third to provide a machine in which the amplifying horn, or a part of it, is put in motion about its longitudinal axis. T hose and other, subsidiary and supplemental, ohjects, the

nature of which hereinafter appears, are

accomplished by means fully disclosed and set forth "iii the following specification, in connection with the accompanying drawings. in detail thereof, following, illustrate the embodiment of my invention in one concrete machine, without being intended to limit the principles of the invention to any particular machine or in any way to restrict the scope of the invention.

In the accompanying drawings,

Figure 1. is a side elevation of the machine.

Fig. 2 is a plan view.

Fig. 3 is a longitudinal central section of the machine on line 3-3 of Fig. 2.

Fig. at is an end elevation of the machine viewed from the line 4-4 of Fig. 1. and 2.

holder, and of providin Such drawings, and the description Fig. 8 is a sectional view of a detail of construction.

The same reference characters indicate the some parts in all the figures.

1n the drawings 1 represents a base or bed to which are secured the i'rumcs 2. and 3 for supporting the record holder: Said frame-s are secured to the base at a distance apart dctcrmii'wd by the length of the record holder, which is supported at its ends by the frames.

As appears best from Fig. 3, the record holder is a tube or cylinder 4: adapted to support records which are indicated at 5, and are shown here as being rings of relatively large diameter and short axial extent. Without limiting myself in any way to the material from which the record holder may be made, I may state that I prefer to make it of some material which is light in weight and is at the same time tough and rigid. The material known as bakclite answers those requirements and is the material which 1 have chosen for this purpose. At

.l'llc ends of the cylinder 4. are mounted rings l3 and T of metal. preferably McAdalnitc metal, for the purposes of providing tracks or runways for the rolls, or other. supporting elements of the supporting frames to occupy, of stiffening and strengthening the gears for driving and being driven, as w-il presently appear. The ring 6 at the left hand end of the record holding cylinder has a lip 8 which is screwed into the end of the cylinder 4, and a shoulder adjacent to such lip adapted to be brought up against the end of the cylinder. In its outcr -surface this rim, has a groove 9 which provides a runway or track occupied by supporting and holding rolls which I am about to describe.

The other ring 7 has an inner lip or flange which is threaded into the opposite end of the cylinder 4 and an outer concentrio lip 10 adapted to lie outside of the cylinder and to form an abutment for the records at one end of the holder. Said lip 10 h'as also it flange or fin 11 which dcfihcs one edge of the runway or track 12. Said ring 7 is also equi ped with a transverse web 13 from which there extends a sleeve 14 concentric with the outer circumference of the ring, on part of which there is formed a worm 15 and on another part of which is formed a worm wheel or spiral gear 16. Said worm and spiral gear are well shown in Fig. 1.

The frames 2 and 3 approximate the form of a semicircumfcrence and thereby embrace the under half of the record holding cylinder. Each frame is equipped with two or more supporting elements such as rolls 17 and 18, shown in Fig. 4, which have ball bearing mounts upon studs 19 and 20, re-

spectively, secured in the frames, and occupy the tracks or runways 0 and 12, respectively, of the end rings of the record holder. These rolls in the two frames pro vide a four point anti-friction support for the record holder whereby the latter is enabled to rotate smoothly, evenly, and silently when driven.

Pivotally connected with each supporting frame is a holding frame, such holding frames being indicated at 21 and 22. The said holdin v frames and supporting frames together, when in the position shown in the drawings, form complete circumferences in closing the ends of the record holder. Tie members extending parallel to the axis of the record holder pass from the frames at one end to corresponding points on the frames at the other end. Such members for the fixed supporting frames are indirated at 23, 24, and 25, the latter serving also as the pivot for the swinging holding frames,- while the tie members for the swinging frames are indicated at 26, 27, 28, and 29. l The members 27, 28 and 29 have" other functions beside that of tying the frames or arms 21 and 22 together, as will pl'rsontl y be shown. Conveniently the members 23, 2-1, 25, and 26 are tubes terminating at their ends at or within the inner faces of the frames to which they are secured by bolts 30 as clearly shown in Fig. 3 in connection with the tie member 24., The construction of the member 25 is somewhat modified from that indicated in order to provide pivots of which the frames or arms 21 and 22 may swing without binding. The ends of said. tie member 25 abut against bushings 31' which pass through the overlapping portion of the fixed and swinging frames. The bolts 30 pass throu 7h such bushings and are threaded into t e tube. The overlapping parts of the fixed and swinging frames, which thus form a knuckle joint or hinge are confined between the head df the bolt 30 and a flange on the end of the bushing 31", said bushing being of such a length that the knuckle oint is not bound or ip ed between the bolt head and flange. ach of the holding frames or arms 21, 22, carries one or more antifriction rolls similar to the rolls 17 and 18,

occupying the tracks of the record holder and serving an anti-friction means to confine the record holder to the supportin rolls. I do not intend to limit the invention to the use of anti-friction means such as the rolls 17,18, and 32 as the sup )orting elements constituting the )arts of the supporting frames which directly engage the record holder, as it is within my conten'iplation to use other elements than rolls, which elements need not be movable relatively to the frames, or even to omit the rolls or equivalents thereof alto ether.

l hen the holding frames are in position as shown in the drawings they are yield; ingly held by spring catches, one of which is shown particularly in Fig. 5. Such catch consists of a dog 33 pivoted to the frame 2 near the upper end thereof and havin a sleeve 34 through which the shank 0% a latch 35 extends. Said la'tch has a handle 36 and a toe 37 adapted to take over a pin 38 on the adjacent end of the swinging frame 21. A spring 39 is interposed bctween the sleeve 34 and the head 40 on the latch shank, thereby drawing the latch against the pin 38. An adjustable stop 41 is provided in the form conveniently ofa screw, threaded through a flange on the end of the swingin frame, and adapted to bear on a hardene' anvil set into the adjacent part of the fixed frame, said adjustable stop being secured in its adjustments by a set screw 42. By these means. the holding rolls of the holding frames may be held always oonti none to the record holder, and be capable 0% yielding in case there should be any irregularities in the shape of the record holder. The latch dog 33 is provided with a'finger 43 adapted to stop against a pin 44 when the latch is released and turned aside. 'Each of the fixed frames 2 and 3 hassuch a latch adapted to engage the cooperating swinging rame.

The swinging frames may be swung up out of the way so as .to leave the record holder unobstructed and enable it to be picked up and removed from the machine for the purpose of placing or removing records. ,When such swinging frames are turned up they move as a unit, being rigidly connected by the tie members previously described, and when turned aside so far as to clear the record holder they are arrested by the coming into contact ofcomplemental shoulders 45, 46 on the fixed and swinging frames.

fine of the important features of the invention is the provision for mounting a plurality of records upon one holder, so that the sounds recorded on all the records may be reproduced in succession without requiring attention until all the records have been In order accomplish this object 'zjlrithout making the record holder unduly long I have designed a new ty e of record,

. which is ring shaped, rather t an c lindriq cal. By this distinction I mean t at the *:diameter of the record is very large n roportion to its axial length. As an in mation of the pro rtions of the records I will say that the diameter may be in the neighbot-hood of nine and one-half inches, while the axial extent may varv from one inch to three or more according to the len h of the record. Ordinarily the length wil be about two inches but in some cases it may be desirable to make the record as long as the en tire holder, as for recording a long speech, etc. The record holder is large enough in dia neter to fit within these ring shaped records and is made long enough to hold as man records as may be desired. Rotation of t e records on the holder is revented f by a spline 47 set into or on the ho der, each of the records having a longitudinal groove 0rd. The machine here illustrated is of that type in' which-the treatment-of the record consists in producing a groove in its surface of irregular depth,,the irregularities corresponding to the sound waves, and in so arranging--thestylus and the diaphra operating arm that the arm is vibrater up and down by the contact of the stylus with the sound groove. I desire to state, however, that the essential features of. my invention are not restricted to a machine of this type.

for I make no claim to any particular sound box or reproducing device and reserve the right to apply the principles of the invention as set forth in the appended claims to other types of machine having other sorts of reproducjng apparatus and inwhich the record may be otherwise prepared, as by laterally undulating or ofi'set grooves.

I will now describe the means for feeding the sound. reproducing device and for conducting it from one record to another, which constitutes another important feature of my invention.

One 'of the members as 27. which I have- -heretof0re' referred to as a tie member. is a lead screw having'bearings in the swinging frames 21 and 22. Coiiperating with and resting upon this lead screw there is a half nut 52 from which an arm 53 leads,

. previously such arm bein connected with the sound box by means 0 cars 54 on the sound box be.- tween which theend of the arm lies, and a in 55 passing through the arm and ears.

he lead screw is rotated synchronously with the record holder by t e worm 15, described, which meshes with a worm wheel 56 on a shaft 57 supported by a bracket 58 which is secured to swinging frame arm 22. Said shaft 57 carries a bevel gear 58 meshin with a bevel gear 59 on the lead screw. has. whenever the record holder is rotated the lead screw is rotated and the sound box is fed along the record holder. The gear ratio of the drive, and the itch of the lead screw are proportioned so tat the sound box progresses at a rate corresponding to the pitch of the groove in the record.

The half nut has a second arm 60 projecting under the rod 28 which I have heretofore referred to as one of the tie members. and carrying an anti-friction roll 62 which rolls alongthe under side of the rod 28. On the adjacent longitudinal rod 29, which is also one of the tie members previously. mentioned, there are mounted collars 63 each of which carries a finger 64 lying under the rod- 28 and constituting a cam projection. That is, the fingers 6 1 while supported independently of the rod 28, yet constitute in effect cam rotuberances onsaid rod. When the ant-iriction roll 62 in traveling along the rod 28 encounters one of these cam protuberances it is depressed, thereby elevating the arm 53 and so for lifting the sound box attached thereto that the stylus is lifted from the surface of the record. These cam rotuberances 64ers rovided in order to ift the stylus in passing from one record to another and to place it properly-in the commencing portion of the next record.

As records or, at least, the grooved surfaces of the records, may vary iin axial length according to the length of the compositions recorded upon them, it is necessary that these cam protuberances be made ad justable, as otherwise the stylus would not:

be lifted at the proper times in all cases to be carried from the end of the groove in one record and laid at the desired point in the record groove of the next record. It is for this reason that the cam protuberances are made separate and are adjustahly mounted upon the rod 29. The collars 63 carrying these cmu fingers are provided with clamping screws 65 by which they may be caused to grip or release the rod 29. Hence each collar may be shifted withits finger 63 into any desired position on the rod '29 and there clumped. Projecting from said collar 33 on the front side of the rod 29 there is another arm 66 formed as a ring or eye in which there .is detachably mounted a lens holder 67 carrying a magnifyinglens. Said tachably connected by record of be carried over the intervening, blank pora screw thread with the internally threaded aperture of the ringshaped arm (36. The cam projection or finger 64' retains the lens holder in the position shown in Figs. 5 and {i with respect to the record holder, the axis of the lens being radial to the holder and the lens being at such a distance from the record thereon as to focuson the record surface. Preferably there is an index mark upon the lens which can be viewed by the operator at the same time that the record groove or a dehnite index mark on the record is seenthrouglr the lens. The purpose of the index mar on the lens is to secure an exact setting of the adjustable cam finger at such a point with relation to the record grooves on two abutting records as to cause the stylus of the sound reproduccr to he lifted from one record at orjust be yond the point where the sound on that record ends, and

tions of the records and deposited in the grtmve of the next record near the point where the record of reproducible sound vibrations on the latter begins. It is to be remembered thatordinarily there is a blank space at each end of a record \vhcrcon either there is no record groove at all. or where there may be a groove which is not of such a character as to vibrate the reproducer in such a way as to produce musical or articulate sounds. The cam causes the reproducer to be held out of contact with the records while passing over the contiguous blank spaces'of two adjacent records so as to avoid causing unnecessary and unpleasant scratching or rasping sounds between the reproduction of the contents of two successive records. By blank spaces in this connection I mean those parts of. the records, whether provided with grmives or not. whereof con-. tact and relative movement with and respect to the reprmluccr will not produce sounds which form any part of the indicated sound contents of the record. Zach of the cam fingers is equipped with a lens havin,- such an index, by the use of which each cam tinhe so set withrespect to the adjager may the stylus to pass cent I'QUOX'dS IIS it) cause from the desired point on each to the de the widths making it uniform sired point on the next. whatever of the various records may, be, unnecessary that the record lie-of a standard ,width. Thereby the machine is adapted to commence not continue the reproduction of the contents of the several records in succession with intervals of silence between the ending of one and the beginning of the next, and without reducing preliminary or intermediate. obectionable sounds.

This provision for adjusting the meansfor lifting the reproducing device in accordance with the varying widths of records is a, novel feature with my invention and is essential to the use of the invention.

The vibrations produced in the diaphragm of the sound box by the stylus are transmitted in the form of sound vibrations through an amplifying horn consistin of the sections 70, Ti, 72, 73 and 74. The%rst of these sections is o onnected to the sound box through acouphng shown in detail in section in Fig. 6,.such coupling being essentially nipple 75 on cal exterior end ofthe therefrom in the form of a segment of spherical shell. This joint permits free play of the sound box when the latter is raised and lowered by the arm 53, which swings in a short are.

The horn sections supported by the section 73, which is an elbow section having a base 77 or pedestal, secured on the machine base 1 near the end of the record holding cylinder but independently of the cylinder and cylinder-supporting frames. I

Horn section 71 is an intermediate section between the fixed section 73 and that section which is connected to the sound box, and is provided so that the connection between the moving sound box and the stationary horn section may be maintained in all positions of the sound box. Consequently, this intermediate section is connected at its ends by swivel joints T8 and 79 with the adjacent sections. Thcse swivel joints are preferably equipped with ball hearings to make the frictional resistance as little as possible. Although the precise nature of the joint is not material to the more important aspects of the invention. yet the joints are in themselves of sullicicnt importance to warrant di tailed description.

The join't- "1". comprises a ring or ferrule screwed on to the elbow end of the born the sound box having a spheriand a sleeve 76 secured to the horn section 70 and pro ecting section 71 and having its mouth internhlly threaded. Screwed into the internal thread of this ferrule is rslceve' 80 having an outwardly turned flange 81. in-the side of which toward the ferrule 79 there is a ball race. Another ball race is formed in the end of ferrule T91 Between this ferrule and the flange 81 is contained the inwardly turned flange 82 of a ring 83 which extends outside of and beyond the flange 81 and is internally threaded to make the screwed connection with the u per end of the horn section 73. A series o balls 84 are contained between the ferrule 79 and flange 8-2, and-another series of balls 85 are contained between the flanges 81 and 8-2. This bearing is of a character which permits separable.attachment' to both of the sections connected thereby, and it also makes provision for adjusta ball and socket joint consisting of a TO, 71 and T2 are all loose nor be bound tootightly. This swivel i by means of a g'joint is "shownin sectional view in Fig. 3.

Both'themembers 79 and 83 are locked to the horn sections whereon they are mounted,

by jmoans of locking screws 3 and t, respectivelyi A The joi'nt 7 8- is shown in detail sectional view ih Fig. 7. It includes a collar 86 screwed upon the exterior of the section 7 0, a collar 87 screwed onthe horn section 71 and an outer sleeve; or ring 78. Ring 86 has a flange 8S projecting between thecollar 87 and a flange 89 do the sleeve or casing 78. lie'twe these flanges and the rin 87 are two sets 6 ,loalls 90 and 91 respective The collar-S 86 nd 87 are adjustable out e horn sections and 71 res ectively, and the ring 78 is adjustable on the collar 87, thus adjusting the bearings for the balls. Collar 86 is then locked by a key 92 on the horn section 70 wh1ch is adapted to enter a notch 93 in the collar 86. The collar 87 and ring 78 are secured together without 'ossibility of impairment of their relative a 'justments lock washer 94, a lock nut 94 and a key 95. The lock washer has an ear 94*} which enters a groove or keyway in the collar 78; the lock nut 9+ is screwed into the threaded interior of rin 78 far enough to hold the washer against t e collar 87,and the key 95 is attached to the lock nut by a screw 95 so as to project into a hole r re ccss in the side of the section 71, all as s iown in Fig. 7.

The twosection's 70 and 71. together are at least as long as the entire length of the machine, whereby the sound box may travel freely to the end of the record most remote from the fixed section 73.

I have referred to the horn section 72 as a separate element. It is separate from the section 71 only in the sense that it ismadc separately for convcnicnce of manufacture. After being assembled with the part 71 these two sections are inseparable and are not relatively movable, so that they become in effect one section. I

The final section 74 of the horn is con taincd in the record holder 4. It may be a flaring member, as shown in Fig. 3, to form a continuation on a gradually enlarging diameter of the other Sm'ilUllS, but it is not necessarily so made. It is within the contmnplation of my invention to leave out any separate element lilo the conical within the record holder and leave the interior of said record holder entirely open whcrcbythe outer walls of the record holder form also the outer walls of the terminal horn section. l-Vhethcr the record holder constitutes the born with or without an internal member like the tube 74, the fact is the same that the terminal horn section extends through the record holder and is rotube 74 tated at all times while the machine is in operation. i

A close joint is made between the sleeve member ll of the record holder, which is the entrance portion of the terminal horn section, and the stationary horn section 73. The abutting ends of this sleeve and the horn section are finished oil on a plane perpendicular to the axis of rotation of the record holder so that practically a tight joint without friction is provided. These mem bers are close together without being actually in contact, and the joint is thus sufliciently tight to avoid any impairment in the volume and quality of sounds delivered from the horn.

It will be understood from the foregoin that the horn section 7 3 with its pedestal 7% constitutes the support for the swinging horn sections and that it is mechanically independent of the terminal section. It will be further understood, however that there is a perfect continuation between all of the horn sections and a gradual enlargement in diameter of the horn, having the same effect as a horn made in one piece with a strai ht axis and uniformly flaring side wa lls. Finally, the inclusion of the terminal section in the record holder permits a saving in space and at the same time enables the terminal opening of the born to be suiliciently large to deliver a. great volume of sound. I have found by experiments that a very lon horn havinga gradual taper to a termina opening of comparatively large diameter gives excellent elfects in the reproduction of sound. My horn, although made in sections, is of substantially the same proportions as such a horn and secures the same effects. It is, however, so built and arranged as to be economical of space and its linal and largest sect ion requires no provision of space whatever because it is within the record holder. Those horn sections should be as light as possible consistent with strength and the proper degree of rigidity. The material which I prefer to use in making them is lllcAdamite metal, which is the lightest material. possessing also the other desirable qualities known to me. 'I wish it to be understood, however. that in mentioning this material. I have not intended to limit myself in any way to the' employment of any particular material or to exclude the use of any other material than that named, in case I should find it desiralhle to use other mate rial.

The applying and removing of records is a simple matter. All that is necessary to be done primarily to change records is to disconnect the sound box from the arm 53 by removing pin 55, to swing the horn section 70, with the sound box, aside. to disconn ct the latches 35, and swing back the swinging holding frames 21 and 22 which are so com nected as to swin in unison. The record holder is then entn'el uncovered and may be lifted from the stationary cradle frames 2 and 3. In beinr thus lifted, it comes away easily from the 1cm section 73, as there are no overlappin joints between this horn section and the record holder. The worm gear 56 for driving the lead screw is removed from the worm 15 by this swinging back of the holding frame. so that such worm gear does not obstruct the removal of the record holder. 'l'hen, records already on the holder may he slipped off and others placed upon it, the key or spline 47 automatically alining the records properly. Thereupon the record holder may be replaced and the holding frame returned. in this replacement of the holder it. is located in exactly the proper position by means of the rolls entering thc track grooves 9 and 12, the flanges flanking such grooves giving the holder the exactly correct position and keeping it from moving endwisc from such position.

When the holding frame is swung back and is arrested by the shoulders 45, 46, after swinging through about 90 of arc, the half nut is then at the side of the lead screw and is not supported by the screw. However. this nut and the sound-box-carrying arms are not allowed to fall out of position. being held both by a strap 96 fastened to the arm and passing under the lead screw, and by a finger 97 which extends over the aide rod 28 on the opposite side of said rod mm the arm 60. Although the strap 96 is near enough to the lead screw to retain the not as described. yet is at the same time far enough below the lead screw to allow the nut 52 to be entirely disengaged from the threads of the screw preliminary to a return of the nut and sound box to the beginning end of the record holder or to any other point when a reproduction of a record is to be commenced.

The described construction of nut and arm illustrated in Fig. (3 thus provides for a positive feed of the sound box when reproducing the record. allows the nut and sound box to be quickly returned to the starting position without depending on a reverse rotation of the lead screw for this purpose. and holds the nut from falling away when the record retaining frame is swung aside.

The machine which I have illustrated is adapted to be mounted upon any sort of a table or stand, and accordingly may mounted upon a cabinet adapted to contain records and inclosing a compartment in which the driving motor is conta ned. I have not shown any driving motor or means in connection with this machine other than the spiral gear 16. It may be considered. h wever. that this gear is typical of any means to which power from a driving motor may be delivered, it being immaterial to the .ion. 'venient location where a shaft carrying such present invention what such motormay be or -how the power is taken from it. I may state, however, that for driving such a spi ral gear 16, the motor would be eq 'pped with a complementally pitched spirz il pin- The motor will be mounted in any 00 a pinion may extend into proximity with the gear 16. That portion of the sleeve 1-1 which is between the worm 15 and the gear 16 (and is designated 150) may serve as a belt pulley to take a driving belt.

I desire to state as regards some aspects of the invention, and particularly that relating to the construction of the record holder so that it may serve as a horn section, it is not essential that the record holder should be cylindrical and of no other shape. I con sider that a construction in which the record holder is tubular with walls other than cylindrical, but havin the other essentials of the combined record holdcr and horn section is within the scope of this aspect of the invention and is covered by those of the following claims which are particularly directed thereto.
